SFEGIFICATION forming part of Letters Patent No. 516,107, dated March 6, 1894. Application led February 6, 1893. Serial No. 461,247. (No model.)

ro This invention relates to certain new and useful improvements in burners for gas, nat

ural or manufactured, and for introducing and mixing crude petroleum oil in conjunction with natural gas and employing either a r steam jet or a blast pressure or compressed air at any suitable pressure to properly consume the carbons contained therein. I find it advantageous though not necessary to pass the air or blast pipe for a short distance 2o through the heated brick-work, thus making the air very hot before mixing with the gas or oil at the point of combustion. I provide a combustion chamber into which leads an inlet for gas and an independent inlet for oil, z 5 and in a direction substantially at right angles thereto an inletfor steam and air. Provision is made for a blast when desired. I

provide shortpipes or tubes leading from the annular chamber or reservoir around the air chamber forward to the outlet into the lire or combustion chamber of the device, which pipes are preferably inclined with relation y to the walls of the chamber and serve to carry and direct the gas well forward and prevent 3 5 return or back flashes to explode or cause explosion outside of the combustion chamber.

Other objects and advantages; oi' theinvention will hereinafter appear and the novel features thereof will be specifically defined by 40 the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which- Figure 1 is a central section through a burner constructed in accordance with my invention. Fig. 2 is an end view thereof. Fig. 3 is a top plan.

Like letters of reference indicate like parts throughout the several views.

Referring now to the details of the drawings by letter, A designates the main or body portion of the device which may be of any suitable size and material, formed with an annular conduit or reservoir a, with which communicates a pipe B for the inlet of gas, and a pipe O for the inlet ot' oil, the said pipes being connected with any suitable source of supply. The passage through the said body portion opposite the conduit or reservoir is contracted as seen in Fig. 1, and the outer end is flaring outwardly as seen in the same view. The wall of the body portion at the points where the pipes are screwed thereinto are enlarged as seen at ct and if desired a collar A may be provided as seen in Figs. 1 and 3. The other end of the body portion is formed with a flange CL2 for connection with the ange 19 of an elbow or coupling B", which in turn is provided with a flange b for connection with the flange c of avertical pipe@ which is tapered in both directions from near the center of its length outward toward the ends as seen in Figs. 1 and 2. W'ithin the outer end of this tapered pipe C extends a steam pipe D which is designed to be connected with some suitable source of supply and provided with a suitable valve or cock by which the flow ot steam therethrough may be regulated as occasion may desire. The steam pipe may be supported in any suitable manner as in the arms of a spider E held to the end of the pipe C and which is provided with passages d for air as seen in Figs. 1 and 3.

F are a plurality of small pipes communieating with the reservoir or conduit a of the body portion and extending forward in an inclined direction toward the mouth of the body portion as seen in Figs. 1 and 2 to conduct the gas from the said reservoir well forward into the flaring mouth as will be seen from Fig. 1.

Suitable means are provided for shutting oft or regulating the blast; I have shown a gate I arranged to slide between the parts A and B and operated by suitable means as a handle or extension i. Another slide or gate may be arranged to entirely shut off the blast when desired or necessary.

It is deemed important that the outlet pipes F incline from the reservoir toward each other in the directions of the discharge end of the device as shown, so as to get'the oil well forward and to prevent explosion as this ar- IOO rangement avoids all danger of the oil or gas getting back into the blast pipes; it also places the oil outlet in the best position for the oil to be converted into spray by the action of the steam or hot blast entering behind said oil outlet pipes thus forcing the oil well forward and by nclining these small pipes anyy leakage of gas or oil after the blast and steam connections are closed will be con-y sumed in the combustion chamber and cannot possibly cause a back draft or explosion in the pipe.

In practice, if the device is to be used in connection with a steam boiler, all that is necessary is to simply out a hole in the furnace door or other portion and bolt or otherwise secure the burner in place; then connect the steam pipe D with a steam supply and connect the gas pipe B with a source of gas. If it is desired to mix crude petroleumr oil with the gas suitable connection is made with the oil pipe O. I have found that natural gas can be both economically and advantageously used where great heat is desired, as in puddfling furnaces and steel melting furnaces, also in heating furnaces of every description, the hot blast will serve to prevent the formation of excess of oxide of iron, or scaling; in cases where the supply of natural gas fails or gives out the crude oil connections give and proves a valuable substitute; all that is necessary to do is to close the gas connection and turn on the crude oil and the operation proceeds as before.

Modifications in detail may be resorted to without departing from the spirit of the in- Vention or sacrificing any of its advantages. Vhat I claim as new isl. The combination with the air chamber with its surrounding reservoir and tapered outlet, of the oil and gas pipes communicating with the reservoir, the steam and air inlets and the small pipes leading from said reservoir in an inclined direction toward each other and toward the center of the outlet, substantially as specied.

2. The combination with the air chamber with its surrounding reservoir and tapered outlet, of the oil and gas pipes communicating with the reservoir, the steam and air -in- 5o lets and the small pipes leading from said reservoir in an inclined direction toward each other and toward the center of the outlet and terminating between the reservoir and the enlarged end of the outlet, substantially as specified.

3. The combination with the body portion having annular reservoir, of the elbow connected therewith and the oppositely tapered pipe jointed to said elbow, the steam and air 6o inlets to the outer end of the double tapered pipe and the oil and gas inlets to the reservoir and inclined small pipes leading from the reservoir toward eachy other and toward the outlet end of the main or body portion, substantially as specified.

4. rlhe combination with the bodyy portion having annular reservoir, of the elbow connected therewith and the oppositely tapered pipe joined to said elbow, the steam and air 7o inlets to the outer end of the double tapered pipe and the oil and gas inlets to the reservoir and inclined small pipes leading from the reservoir toward each other and toward the outlet end of the main or body portion, said pipes extending in a direction opposite to the taper of the outlet and terminating within the same, substantially as specified.

5. The combination with the body portion having annular reservoir, of the elbow con- 8o nected therewith and the oppositely tapered pipe joined to said elbow, the steam and air inlets to the outer end of the double tapered pipe and the oil and gas inlets to the reservoir and inclined small pipes leading from the reservoir toward each other and toward the outlet end of the main or body portion and the sliding gate arranged between the res ervoir and the doubled tapered pipe at the junction of the main or body portion and the 9o elbow, substantially as specified.

In testimony whereofIafIiX my signature in presence of two witnesses.
